About T75.0

T75.0 is the ICD-10-CM diagnosis code for effects of lightning. It belongs to category T75 (other and unspecified effects of other external causes), block T66-T78 (other and unspecified effects of external causes) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T75 (other and unspecified effects of other external causes), T75.0 is specifically for effects of lightning. Related codes cover unspecified effects of drowning and nonfatal submersion (T75.1), effects of vibration (T75.2), motion sickness (T75.3), electrocution (T75.4) and other specified effects of external causes (T75.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
